Given the function:
\(F(x)=\frac{x+4}{x^2+5x-24}\)Let's find the values of x where the graph of the function has a vertical asymptote.
Let's factor the denominator using the AC method.
Find a pair of numbers whose sum is 5 and whose product is -24.
We have:
8 and -3
Thus, the function will be:
\(F(x)=\frac{x+4}{(x+8)(x-3)}\)The vertical asymptote(s) are the values of x where the function is undefined.
Thus, they are the values where the denominator will tend to zero.
Write each factor in the denominator to zero and solve for x.
We have:
• x + 8 = 0
Subtract 8 from both sides:
x + 8 - 8 = 0 - 8
x = -8
• x - 3 = 0
Add 3 to both sides:
x - 3 + 3 = 0 + 3
x = 3
Therefore, the values of x where the function have a vertical asymptote is:
x = -8 and x = 3
ANSWER:
• C. x = 3
• D. x = -8

How many different numbers can be obtained using five binary bits? A)64 B)32 C)31 D)63.
In binary representation, each bit can be either 0 or 1. Using five binary bits, we can obtain 32 different numbers. Therefore, the correct answer is (B).
With five binary bits, we have five positions, and each position can have two possibilities (0 or 1). To calculate the total number of different numbers we can obtain, we need to raise 2 to the power of the number of bits. In this case, we have \(2^5,\) which equals 32. Therefore, we can obtain 32 different numbers using five binary bits. To understand this concept, we can think of each binary bit as a switch that can be either on (1) or off (0). With five switches, we have a total of 32 different combinations or numbers that can be represented. These numbers range from 0 (all switches off) to 31 (all switches on). Therefore, the correct answer is (B), which states that we can obtain 32 different numbers using five binary bits.

Compute the value of x from the cross-section notes shown if the width of roadway is 9m with side slope of 1:1 cross-sectional notes 5.42/+0.92 +4.25 +X/0.60 a) 4.9 b) 4.82 c) 5.60 d) 5.1
The value of x from the given cross-section notes, if the width of roadway is 9m with side slope of 1:1, is 5.60 (option c).
Let us see how we can compute the value of x from the given cross-sectional notes. We are given that:
Width of roadway is 9m
Side slope is 1:1
The cross-sectional notes are:
5.42/+0.92+4.25+X/0.60
From the given cross-sectional notes, we can see that the left-hand side slope is +0.92 and the right-hand side slope is -0.60 (as the right-hand side is below the axis).
Let us now consider the left-hand side of the cross-section:
5.42/+0.92.
The elevation at the left edge is 5.42 m and the side slope is 1:1. Therefore, the width of this part will be:
width = elevation/slope
= 5.42/1
= 5.42 m
Now, let us consider the right-hand side of the cross-section: +4.25+X/0.60
The elevation at the right edge is +4.25 m and the side slope is 1:1. Therefore, the width of this part will be:
width = elevation/slope
= 4.25/1
= 4.25 m
The total width of the road will be the sum of the widths of the left and right parts:
total width = 5.42 + 4.25
= 9.67 m
We are given that the width of the road is 9 m. Therefore, we need to reduce the value of x such that the total width becomes 9 m:
9 = 5.42 + 4.25 + x/0.609
= 9 - 5.42 - 4.259
= 0.30 * 0.60x
= 0.18 + 4.25x
= 4.43 m
Now, we can find the total width:
total width = 5.42 + 4.25 + 4.43/0.60
total width = 5.42 + 4.25 + 7.38
total width = 16.05 m
Therefore, the value of x is:
total width - (width of left part + width of right part) = 16.05 - 9.67
= 6.38 m
Now we can convert the value of x to a ratio using the side slope:
+X/0.60 = 6.38/0.60
X = 3.83
Therefore, the ratio of the side slope is 3.83:0.60 = 6.38:1
The value of x from the given cross-section notes, if the width of roadway is 9m with side slope of 1:1, is 5.60 (option c).

The y-coordinate for the solution to the system of equations is -3.
What is a system of equations?
A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations. The intersection of two lines represents the system of equations' solution.
Given system of equations are,
6x + 11y = -3
4x + y = 17
To solve these equations, we must first remove x or y terms.
To do this we must make the removing term's coefficients the same.
In this case, let's remove y.
We are multiplying the second equation by 11. Then,
6x + 11y = -3
44x + 11y = 187
Now we will subtract the second equation from the first.
- 38x = -190
x = 5
Now to find y, substitute x in any one of the equations.
6 * 5 + 11y = -3
11y = -33
y = -3
Hence the y-coordinate for the solution to the system of equations is -3.

When n = 2
\(f(2) = -10 + 6(2-1) = -10 + 6*1 = -10 + 6 = -4\)
When n=3
\(f(3) = -10 + 6(3-1) = -10 + 6*2 = -10 + 12 = 2\)
When n = 4
\(f(4) = -10 + 6(4-1) = -10 + 6*3 = -10 + 18 = 8\)

Can the sides of a triangle have lengths 3, 7, and 11?
The sum of the lengths of the two smaller sides is not greater than the length of the largest side. Therefore, a triangle with side lengths of 3, 7, and 11 cannot exist.
To determine if the sides of a triangle can have lengths 3, 7, and 11, we can use the triangle inequality theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.In this case, let's compare the sum of the two smaller sides (3 and 7) to the largest side (11).3 + 7 = 10 < 11.
Therefore, the sum of the lengths of the two smaller sides is not greater than the length of the largest side.
Therefore, a triangle with side lengths of 3, 7, and 11 cannot exist.
This makes sense because if we try to draw a triangle with these side lengths, we would find that the two shorter sides cannot connect to form a triangle with the longer side.

Procter and Gamble (PG) paid an annual dividend of $2.95 in 2018. You expect PG to increase its dividends by 7.4% per year for the next five years (through 2023), and thereafter by 2.6% per year. If the appropriate equity cost of capital for Procter and Gamble is 8.6% per year, use the dividend-discount model to estimate its value per share at the end of 2018.
The dividend in 2018 was $2.95, and it is expected to grow at a rate of 7.4% for the next five years and 2.6% thereafter. With an equity cost of capital of 8.6%, the value per share at the end of 2018 can be calculated.
To calculate the value per share at the end of 2018, we need to discount the expected future dividends using the dividend-discount model. The model assumes that the value of a stock is equal to the present value of all its expected future dividends.
First, we need to calculate the dividends for each year from 2019 to 2023. We start with the dividend in 2018, which was $2.95. We then increase it by 7.4% each year for the next five years:
Dividend in 2019 = $2.95 * (1 + 7.4%) = $3.17
Dividend in 2020 = $3.17 * (1 + 7.4%) = $3.40
Dividend in 2021 = $3.40 * (1 + 7.4%) = $3.65
Dividend in 2022 = $3.65 * (1 + 7.4%) = $3.92
Dividend in 2023 = $3.92 * (1 + 7.4%) = $4.22
After 2023, the dividend is expected to grow at a rate of 2.6% per year. To find the value per share at the end of 2018, we discount the future dividends to their present value using the equity cost of capital of 8.6%.
The present value of the dividends can be calculated as follows:
PV = (D1 / (1 + r)) + (D2 / (1 + r)^2) + ... + (Dn / (1 + r)^n)
where PV is the present value, D1 to Dn are the dividends for each year, r is the equity cost of capital, and n is the number of years.
In this case, n = 5 because we are discounting the dividends for the next five years. Let's calculate the present value:
PV = ($3.17 / (1 + 8.6%)) + ($3.40 / (1 + 8.6%)^2) + ($3.65 / (1 + 8.6%)^3) + ($3.92 / (1 + 8.6%)^4) + ($4.22 / (1 + 8.6%)^5)
PV = $3.17 / 1.086 + $3.40 / 1.086^2 + $3.65 / 1.086^3 + $3.92 / 1.086^4 + $4.22 / 1.086^5
PV ≈ $2.91 + $3.07 + $3.24 + $3.41 + $3.59
PV ≈ $16.22
Therefore, the estimated value per share of Procter and Gamble at the end of 2018 using the dividend-discount model is approximately $16.22.

y – 10 = 11x + x2
y – 12x = 30
The first solution is (–4, –18).
The second solution is (
,
).
Answer:
(-4,-18) and (5,90)
Step-by-step explanation:
I'll assume the first equation is supposed to be y – 10 = 11x + x^2
This is a parabola. The second equation is a straight line:
y – 12x = 30
We want to find the points at which these lines intersect. They will intersect for any (x,y) that
Let's rearrange the second equation to isolate y:
y – 12x = 30
y = 30 + 12x
Now we can take the this value of y and substitute it into the first equation:
y – 10 = 11x + x^2
(30 + 12x) – 10 = 11x + x^2
20 + 12x = 11x + x^2
0 = x^2 -x -20
We can factor this into (x+4)(x-5)
That means x can be either -4 or 5.
Find the value of y using these values of x in both original equations:
For x = -4
y – 10 = 11x + x^2
y = 11x + x^2 + 10
y = 11(-4)+(-4)^2 +10
y = -44 + 16 + 10
y = -18 The point both lines meet is at (-4, -18) which was already given in the problem.
For x = 5
y – 10 = 11x + x^2
y = 11x + x^2 + 10
y = 11(5) + (5)^2 + 10
y = 55 + 25 + 10
y = 90
The second point both lines meet is (5,90).
We should use both solutions in the second equation to verify these values, but I'll graph them, instead. See the attached graph to prove these points are correct.
the american college of obstetricians and gynecologists reports that 32% of all births in the united states take place by caesarian section each year. ( national vital statistics reports , mar. 2010). a. in a random sample of 1,000 births, how many, on average, will take place by caesarian section? b. what is the standard deviation of the number of caesarian section births in a sample of 1,000 births? c. use your answers to parts a and b to form an interval that is likely to contain the number of caesarian section births in a sample of 1,000 births
a. In a random sample of 1,000 births, the expected number of births that take place by Caesarian section is:
E(X) = n*p = 1,000 * 0.32 = 320 births
Therefore, on average, 320 births out of 1,000 will take place by Caesarian section.
b. The variance of the number of Caesarian section births in a sample of 1,000 births is:
Var(X) = np(1-p) = 1,000 * 0.32 * (1-0.32) = 217.60
The standard deviation is the square root of the variance:
SD(X) = sqrt(Var(X)) = sqrt(217.60) = 14.76
Therefore, the standard deviation of the number of Caesarian section births in a sample of 1,000 births is 14.76.
c. To form an interval that is likely to contain the number of Caesarian section births in a sample of 1,000 births, we can use the normal distribution and the central limit theorem. Since n*p = 320 is greater than 10, we can assume that the distribution of the number of Caesarian section births in a sample of 1,000 births is approximately normal.
The 95% confidence interval for the number of Caesarian section births is:
320 ± 1.96*(14.76) = (291.16, 348.84)

A down arrow is drawn with its tip at (2, 0). Then it undergoes a translation described bythe directed line segment (−3, 1). What direction is the arrow pointing?
Answer:
down
Step-by-step explanation:
In mathematics a when dealing with graphs a translation is basically just moving points left/right and up/down but it does not change the shape of the original figure in any way just moves its position. In this scenario, the down arrow's tip will be moved from point (2,0) to (-3,1) but the arrow will still be the same size and still be pointing downward.

i am a number less than 3,000.when you divide me by 32, my remainder is 30. when you divide me by 58, my remainder is 44. what number am i?
The number less than 3,000.when you divide me by 32, my remainder is 30. when you divide me by 58, my remainder is 44 is one of this {798, 1726, 2654}.
There exists a, b∈N such as
N= 30+32a=44+58b
Therefore,
16a-29b= 22-15=7
Let us notice that 5×29-9×16=1
Therefore, 35×29-63×16=7
Hence, a= -63 is a non-fundamental solution to our equation.
We can show that the other solution are of the form a=-63+29k, with k∈Z
Therefore, the first positive solutions are
a= -63+3×29= 24
N= 798
a= -63+4×29= 53
N= 1726
a= -63+5×29=82
N= -63+6×29= 111
N= 3582
Therefore, the number is one of {798, 1726, 2654}.

Rachel, adam, michelle, hannah, and james are going to the movies. They have $65 to spend on tickets and snacks. Each movie ticket costs $9. 50, and each snack item costs $4. 50. How many snacks can they buy to split among them?.
The number of snacks they can buy to split among them is 3.
Rachel, Adam, Michelle, Hannah, and James are going to the movies. They have $65 to spend on tickets and snacks. Each movie ticket costs $9.5, and each snack item costs $4.5. We need to calculate the number of snacks they can buy.
Let the number of snacks they can buy be represented by the variable "n". The total money is $65. The amount of money left after buying movie tickets for all the people is calculated below.
C = 65 - 5*9.5
C = 65 - 47.5
C = 17.5
Hence, they have $17.5 to spend on snacks. The number of snacks they can buy is determined by the ratio of the money left to the price of each snack.
n = 17.5/4.5
n = 3.89
They can buy the snacks in whole numbers. Hence, the number of snacks they can buy is 3.
